An ideal otto cycle has a compression ratio of 8. at the beginning of the compressionprocessp= 100 kpa andt= 30◦c. the maximum cycle temperature is 1000◦c.
(a)find the temperature, pressure and specific volume at states 1,2,3,and 4.
(b) find theheat supplied, heat rejected, work done by the system, work done on the system, network done, and thermal efficiency.
(c) calculate the thermal efficiency of a carnot cycleoperating between the same temperature limits.
(d) calculate the change in entropyof the working fluid for (i) the combustion process, and (ii) the exhaust process.
(e)sketch thep−vandt−sdiagrams.
